General tips
Eggs are the precision showcase of sous vide. A 1°F change between 145°F and 149°F produces a visibly different texture - from liquid yolk with barely-set whites to firm whites with a jammy center. No other protein responds this dramatically to small temperature changes.
Cook eggs directly in the shell - no bag needed. The shell is a natural sealed container that handles sous vide temperatures perfectly.
For ramen eggs, cook at 148°F for 1 h, then ice-bath and marinate in soy-mirin for 4–24 h. The marinade penetrates the set whites and seasons the yolk.
Batch-cook eggs for meal prep. Cook a dozen at your preferred temperature, ice-bath, and refrigerate in-shell for up to 5 days. Rewarm at 130°F for 10 min before serving.
Anti-tip: do not hold eggs at temperature for more than 2 h. Unlike meat, egg proteins continue to set and the texture shifts from custardy to chalky. Set a timer and pull on time.
Barely Set tips
Mark shells with a pencil before cooking so you know which eggs were sous vide.
Peel under running water once chilled to gently remove any thin whites.
Warm peeled eggs for 2 min in 135°F water if serving hot after chilling.
63° Egg tips
Score the shell gently before peeling to avoid tearing the delicate white.
Keep eggs in the bath until plating so they stay warm and jammy.
Use a spoon to scoop the egg out if peeling is finicky; the membrane holds it together.
Soft-Boiled tips
To peel cleanly, tap the wider end to break the air pocket, then roll gently under your palm.
For transport, keep in-shell eggs in cold water inside the fridge.
Warm peeled eggs in 135°F water for 5 min to restore that just-cooked feel.
